Welding of magnetic gaskets for refrigeration
Welded magnetic gaskets made of soft PVC – manufactured to measure according to the customer's specification. They close the doors of refrigeration equipment tightly, cut cold losses and lower energy consumption. A technology of RefPlast, a brand of the AiFO Group.
Why the gasket matters
A tight seal means a lower bill
A worn or badly matched gasket leaks cold around the clock. The unit runs longer, and frost and condensation build up on the door frame.
We weld the gasket to measure, matched to the specific profile and magnetic insert, so a replacement requires no change to the door structure.
What we make
Gaskets and magnetic inserts
Magnetic gaskets
Welded to the customer's specification – they close the appliance tightly and deliver real energy savings.
Gasket PU-090
Soft PVC, welded to measure, compatible with the magnetic insert PU-M8,9x2,7.
Gasket PU-033
Soft PVC, welded to measure, compatible with the magnetic insert PU-M11,6x3,0.
Gasket PU-088
Soft PVC, welded to measure, compatible with the magnetic insert PU-M8,9x2,7.
What you gain
Why our gaskets hold
Resistant to frost
The gaskets work in cold and freezer rooms – they stay flexible at low temperatures.
A strong magnet
We use inserts with a pull force of up to 55 g/cm, so the door closes firmly throughout the appliance's life.
Complex cross-sections
We produce gaskets with complicated profiles, matched even to unusual frames and door surrounds.
Made to measure
We weld the gasket exactly to the dimensions supplied by the customer – short runs included.
Choice of polarity
S-N-S as standard and, to individual order, N-S-N as well, so the gasket works with your existing system.
Every weld inspected
The operator checks the quality of the weld at the station, and the finished gasket also goes through a dimensional check.

Production process
From granulate to a packed gasket
We take the gasket through the whole route – from profile extrusion, through cutting, magnetisation and welding, to quality control and packing.
-
Extrusion
Extruding the gasket profile from soft PVC – the first stage of the whole production run.
-
Cutting
The profile is cut to the exact lengths given in the order specification.
-
Magnetisation
Magnetising the insert with S-N-S polarity or – on request – N-S-N.
-
Welding
Joining the corners on semi-automatic welding machines; the operator inspects every weld.
-
Quality control
Verification of the dimensions and tightness of the finished gasket before packing.
-
Packing
The gaskets are protected for transport so that they arrive without deformation.
Applications
Where our gaskets work
- Cold room doors
- Refrigerated doors and display cases
- Freezer cabinets and counters
- Catering furniture

FAQ
Frequently asked questions about magnetic gaskets
Did not find your answer? Write to us – we will match a gasket to your appliance.
Ask a questionWhat is a magnetic gasket?
It is a soft PVC gasket with a magnetic insert embedded inside. The magnet pulls the door against the frame of the appliance, so the closure is tight and cold does not escape into the room.
What pull force do your magnetic inserts have?
We use inserts with a pull force of up to 55 g/cm. The exact value is matched to the weight of the door and the operating temperature of the appliance.
Will you make a gasket to measure?
Yes. We weld gaskets to the customer's specification – just give us the outside dimensions, the profile type and the magnetic insert the gasket has to work with.
What polarity do the gaskets have?
S-N-S polarity is the standard. To individual order we also make gaskets with N-S-N polarity.
Do the gaskets withstand low temperatures?
Yes. We produce welded gaskets resistant to low temperatures, intended also for freezer rooms and cabinets.
Can you supply a profile that fits the gasket?
Yes. The RefPlast range includes PVC profiles compatible with the gaskets we manufacture – we supply the set, not a single part.
